tikzplot42 0.3.0

TikzPlot to make TikZ/PGFPlots plots with matplotlib.pyplot-like syntax.

TikzPlot

A clean version of PltToTikz, this time as Python package. Easy to use: only replace import matplotlib.pyplot with this library.

Please let me know if you find any bugs or unexpected behaviour. Examples may be found in repository under tests/ directory.

Installation

NEW: PyPI: pip install tikzplot42. Alternativley, download this package and install using: pip install [path], where [path] is the path to the directory, containing pyproject.toml.

Python usage

Instead of using import matplotlib.pyplot (as plt), use import tikzplot.plots (as plt).

LaTeX requirements

• \usepackage{tikz},
• \usepackage{pgfplots},
• \pgfplotsset{compat=1.18} (may be lower, but compilation is not guaranteed),
• \usepgfplotslibrary{fillbetween} (if you use fill-between plots),
• \usepgfplotslibrary{groupplots} (recommended for best results, enabled by default, may be avoided by setting TikzConfig USE_GROUPPLOTS=False),
• \usepackage{xcolor} (recommended for best colors, works without but needs change of TikzConfig USE_XCOLOR=False).

Export using plt.savefig("example_graph.tex") (recommended) or plt.show(). Then use the generated file as \input{example_graph.tex}.

Currently implemented:

Some basic plot commands are already implemented with commonly used arguments:

Plotting

• plot(),
• scatter(),
• loglog(),
• semilogx()/semilogy(),
• errorbar(),
• stem(),
• fill-between(),
• hlines()/vlines(),
• historgam(),
• imshow().

Figures

• plt.figure() (currently only to give you figure object or to set figsize),
• plt.subplot(), plt.subplots() (with sharex/sharey fully implemented, projection polar and 3d with basic support),
• set_size_inches().

Styles

If axes and plot have different name for command with same effect, both are implemented (e.g. plt.xlim() and ax.set_xlim()).

• grid(),
• xlabel()/ylabel(),
• xlim(), ylim(),
• xscale("log")/yscale("log"),
• xticks()/yticks(),
• ax.set_xticklabels()/ax.set_yticklabels(),
• legend() (basic position control),
• ax.twinx(),
• ax.set().

Supported common **kwargs

• color/c (all matplotlib formats, except color schemes which are not yet implemented),
• linestyle/ls,
• linewidth/ls,
• fmt,
• marker,
• marksize/ms,
• alpha,
• label.

Colorbars

Colorbars and colormaps are implemented a bit differently than in matplotlib (simplified):

• if you use imshow(), you may use its return in Colorbar() (which you have to import as from tikzplot import Colorbar),
• you may use Colorbar(axis, cmap, lower, upper, ...) for manual colorbar. Additional kwargs may also be used by imshow() return.

TikzConfig

For plot configurations (default sizes, paddings, etc.), use from tikzplot import TikzConfig:

• modifyParam(PARAM=value) (for runtime session setting),
• setPermanent(PARAM=value) (for user defined default value). Currently supported parameters are listed with their default values in src/tikzplot/config.py.

More features coming soon...

• basic color schemes,
• improved 3D plots (currently only basic support: plot, errorbar, fill_between, scatter, plot_wireframe, plot_surface),
• ...
